Did I Finally See a UFO?!

Any of you who know me, know I'm totally fascinated with ghosts, UFOs, bigfoot - anything weird or bizarre.  I would love to experience any of these oddities.
Well, I may have done so but I just don't know.

I wake up early, usually between 5am and 6am.  The other morning I woke up at 5:30 and turned on the tv to watch the Olympics.  On the side of our rental we have French doors that look out over the foothills with a few homes on acreages just across Dry Creek Rd.

I was watching tv when I noticed (it was still very dark outside) out of the corner of my eye, an orange object that looked to be about the size of a marble (from here) moving horizontally across the window.  I thought it must be a reflection.  Nothing on the tv was orange and I didn't have any lights on in the house.  I watched it for a minute never taking my eyes off it because I couldn't figure out what it was.  There are no roads over there.  Finally I got up and walked over to the glass door and peered out.

I cupped my hands around my eyes and watched as this orange glowing "orb" moved slowing between our house and the foothills.  It went behind a tree and then came out the other side, then, changed to white - like a headlight but not nearly as bright.  I couldn't believe my eyes because I knew after plastering my face against the window that it was definitely not a reflection of something.  There was something there.

I ran the few steps to grab the binocs and when I looked back it was gone.  I looked through the binocs for a long time trying to find it again but couldn't.  I have no idea what I saw but it was weird.

Below is a picture.  I didn't take this picture, it was on the internet, but this is exactly what it looked like.
